Mopar (a simple contraction of the words MOtor and PARts) was trademarked for a line of antifreeze products in 1937. It also was widely used as a moniker for the CMPC. The Mopar brand made its mark in the 1960s—the muscle-car era. The Chrysler Corporation built race-ready Dodge and Plymouth “package cars” equipped with special high-performance parts. Mopar carried a line of “special parts” for super stock drag racers and developed its racing parts division called Mopar Performance Parts to enhance speed and handling for both road and racing use.
